And the Levite, the husband of the woman that was slain, answered and said, I came into Gibeah that belongeth to Benjamin, I and my concubine, to lodge. And the men of Gibeah rose against me, and beset the house round about upon me by night, and thought to have slain me: and my concubine have they forced, that she is dead. And I took my concubine, and cut her in pieces, and sent her throughout all the country of the inheritance of Israel: for they have committed lewdness and folly in Israel.
